Hikvision DS-KB2421T-IM Four-Wire Video Door Station
The Hikvision DS-KB2421T-IM is an outdoor video door station for compatible Hikvision four-wire analogue intercom systems. It provides one-touch calling, two-way audio, infrared-assisted video and a relay output for compatible electric-lock control.
Best For
Replacing or adding an outdoor entrance station to a compatible Hikvision four-wire intercom system, including installations using a DS-KH2220 indoor monitor or the DS-KIS203T system family.
Important: This listing is for the outdoor door station only. It is not a complete intercom kit and cannot operate by itself. A compatible indoor monitor, 12 V DC power, four-core cabling and professional installation are required.

- Compatible applications using the DS-KH2220 indoor station

This is an analogue component, not an IP or Wi-Fi door station. It does not provide smartphone app access as a standalone product. Please confirm the existing monitor, wiring and power supply before ordering, particularly when replacing the earlier DS-KB2421-IM.
